RE: metal rack for staining dishes

Dear Histonetters,
I have been using Tissue-Tek staining dishes (both the transparent and green
ones) for different staining protocols. We have stainless steel wire racks
which hold 3 of these staining dishes.
We purchased these racks many years ago from Columbia Diagnostics. Now we
need more of these racks, they provide more flexibility and take up way less
space than the original 3-feet-long Tissue-Tek rack. Unfortunately Columbia
does not carry these racks any more so I was told. Does anybody know another
source for these racks or a similar rack to be used with Tissue-Tek staining
dishes?
Sincerely,
Laszlo
